The system of blast furnace pulverized coal has been widely used in Electric Power, Steel and Metallurgical industry etc. In the whole system, the preparation of pulverized coal is the most important step. Common mill can't satisfy the needs of pulverized coal due to its high demand and big capacity. So more and more customers are inclined to largescale coal mill.
Coal is the mainly energy consumption, so it is the main problem to improve coal fired efficiency for thermal power plant. Traditional ball bill has large power consumption in the process of production, and fineness of pulverized coal is not up to the standard. Great Wall Machinery put forward coal vertical roller mill solution for power plant, which can effectively improve .

· pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner panels.
Inside the power station, the coal is pulverised to a fine powder in giant grinding mills. This is because pulverised coal burns quickly, like gas. The pulverised coal is transported to the boiler furnace with air where it burns. Boilers, as high as a 35storey office block, are the rectangular blocks that give power stations their distinctive ...
Coal pulverizers are used extensively within industries that operate coal fired furnaces, this includes the power generation and steel industries. Note: Vertical grinding mills are used extensively within the cement industry. Vertical Grinding Mill Components A vertical grinding mill consists of the following components:
